SPRINKLER DEVICE FOR LOCOMOTIVES.

first of the objects of this present inventionis the construction of a device of the character specified which will provide in a com pact, etficient, and simple form, a means for using a limited or predetermined quantity of water in the tank in the manner indicated, and at the same time will not be liable to scald or injure the fireman, engineer, or bystanders, through the back flow of steam or hot water, as frequently happens in connection with the arrangement in common use in which a sprinkler hose is connected to the injector mechanism in such posltiml that it the injector breaks or backs up, the steam or hot water will flow out through the sprinkler hose-an occurrence which is not at all uncommon.

In order that my invention may he better understood. l have illustrated the same in pi-eternal form in the accompanying drawings. wherein-- Figure 1 is a A artial plan view showing a locomotive tender construction with my improvements applied thereto; Fig. 2 is an elevation partly in section, showing a side view oi? the apparatus shown in Fig. 1; Fig. is an end :WillOlltll view with part of the apparatusin levation; Fig. it is a detail of one form of valve mechanism I employ, and Fig. 5 is lother view of the valve device shown in rig. 1-.

Referring now more particularly to Figs. '1, 2, and 3, it will be seen that in the lower portion ol the tender therein indicated I have located a tank 6 which in order to reduce corrosion to a minimum is preferably made of cast metal and is located at or adjacent to the bottom of the water containing portion or the tank or tender, and is made preferably of small 'VQltlCttl dimension. but considerablesize laterally and longitudinally so as to be capable of containng a sufficient quantity of water for an or Specification of Letters Patent.

dinary sprinkling operation. This tank is 1n general a closed receptacle except for the provision therein of an outlet pipe 7 which starts near the bottom of the tankand extends .upwardly to a point normally above the ordinary height of the water and is connected with a sprinkler hose 8. Another connection to the tank is through the valvular device 9 which is coupled up with the pipe 10 that supplies air pressure to the tank through a manually controlled threeway cock or valve device 11 that has aisupply from some convenient source of air pressure, as for example the main reservoir of the air lnakesystem not shown in the drawings but well known in the art. The valvular device 11 should be "located somewhere withineonvenient reach of the fireman or person operating the sprinkler.

As is evident from examination of Fig-- ures l and 5, the valvular device 9 com-.

prises primarily a casing 12 to which there is connected the air inlet pipe 10. 'Within the casing 12 is arranged a piston 1-t having a valve 15 connected therewith in position to close the water inlet opening 16 when the parts are in the position shown in Figure 4, but to open when the piston is depressed to its lower1nost position in the chamber of the-casing 12, and allow water to How freely down through the opening 16 and out laterallv through the series of openings 17 to fill the water receptacle 6 from the water in the tender or tank.

Arranged at a suitable pointwithin the cylinder of the casing 12 there is another opening 18 which is uncovered when the piston is in its uppermost position with the valve 1:? closed, sons to allow the air which has closed the valve 15 to flow out through the passage 19 and expand in the, upper portion of the water'receptacle 6, exerting a downward pressure upon the water therein, such as will drive the water out through the pipe? and sprinkling hose 8.

The operation of my invention is as follows \Vith the parts arranged as shown, when it is desired to sprinkle the coal or use the sprinkling device, the threeway cock or manually controlled means 11 is turned so as to admit air from the main reservoir or other air supply source to the inlet-pipe 10, thence to the casing 12 whereupon it acts against the piston 14 to force the piston up ward and seat the valve 15 uncovering the port 18 and flowing around through the pusa the air to escape-from the receptacle 6 andsage 19 to fill the u per part of the water reservoir or receptac e 6, and the water from the main tender .ortank 'bein thus cutoff, the pressure confined withm the closed water receptacle 6 will force. the water out through the pipe 7 and: the spirin? kler hose 8 in a stream'that will continue to: flow until substantially all the water, or

nearly all'thewa'ter, in the closed rece tacle 6 has been discharged, the receptacle eing' made of at least-suificient size to supply the requirements of any. ordinary sprin ling operation; When t e sprinkling is to be u i stopped the valvell is closed and the lateral V vent or three-way opening 11' therein allows the underside of the piston, which latter then descends, the water above the valve 15 flowing downward and laterally through the cle 6 ready-for 'anot passage 17 and promptly filling the re,cept a er operation.

' It will be evident-from examination ofthe action of the above mechanism that the ad-' mission of water to the'r'eceptacle .6 is substantially co-incidentwith the closure of the air supply which has beenu'sed in sprinkling, and vice versa that is to say, that as .soon as the air sup ly is admitted'through the valve 11 the va vular device 9 will automatieally operate to out 01f the water con-' nection from the main tank to the closed receptacle or reservoir 6.-' While I prefer.

the arrangement of valve device shown, it is ObVlOllS t at other specific embodiments of valvular mechanism could be utilized to obtain the same operations and relations between the manual-controlling means for the 1.
